We have a new block that's called the if/else block. It's a conditional statement just like
the if block you've used in the puzzles before. But now there's a new part at the bottom that
says else. The if/else block lets the bee make a decision between two sets of actions.
If the bee is at a flower, the bee will do the set of actions you put in the first part
where it says do. If the bee is not at a flower, the bee will do the set of actions you put
in the slot where it says else. If statements are how computers are able to make decisions.
Humans set up conditions for the computer that say if the computer is presented with
a certain situation do this. Else, which just means otherwise, do that. The top of our if/else
block says if at flower. But the top of our block could say other things, like if nectar
equals 2 or if there's a path ahead, our block will behave in the same way. That if the statement
at the top is true it will do the first set of actions. But if the statement at the top
is false, it will do the second set of actions.
